PSITTACI. 
ScHLEGEL, H. Museum d^Histoire Naturelle des Pays-Bas. 
Livraison. Psittaci. Leyde : 1864. Royal 8vo, pp. 166. 
The genera into which the author divides the Psittaci are 
Araraj Coniirus, Psittaculus, Psittacus, EclectuSj Aniazona, 
Psittacula, PalceorniSy PlatycercuSy Euphema, Strigopsis, TricTio- 
glossus, Nanodes, LoriuSj LoriculuSy Cacatua, Microglossmif 
CalyptorhynchuSj and Nestor. According to the synopsis at the 
end of the catalogue, we find that the Leyden Museum contains 
1204 examples (including osteological specimens) of 259 species 
of birds of this order. Lesson^s term Amazona is used for a 
comprehensive group of tropical American Parrots, including 
the older genera Chrysotis (in part), Piontis and others, which 
vary in size between Corvus frugilegus and Tardus merulay with a 
rather rounded tail, tolerably short, rarely very short, or a little 
elongated. For the precise boundaries of Professor SchlegeFs 
other groups we must refer our readers to the work itself, as 
well as for the details of his unification of many of the species
